This discussion provides an understanding of the difference between a Radio Frequency Discharge and Dielectric Barrier Discharge in an excimer lamp
Not what you're looking for?
This discussion provides a good understanding of the difference between Radio Frequency Discharge (RFD) and Dielectric Barrier Discharge (DBD) in an excimer lamp. Qualitatively speaking, micro-plasmas are formed in a DBD (which are thread-like in structure). These thread-like plasmas generate irregular light emission (flickering light). In the case of a RF discharge, a plasma is formed uniformly between the dielectric material, resulting in a very uniform emission of light (spatially and temporarily), i.e., no flickering light.

This discussion provides a good understanding of the difference between Radio Frequency Discharge (RFD) and Dielectric Barrier Discharge (DBD) in an excimer lamp (see Figure 1). Qualitatively speaking, micro-plasmas1) are formed in a DBD (which are thread-like in structure). These thread-like plasmas generate irregular light emission (flickering light). In the case of a RF discharge, a plasma is formed uniformly between the dielectric material, resulting in a very uniform emission of light (spatially and temporarily), i.e., no flickering light.
